TRACK-GRINDING MACHINE.

T 0 all whom it may concern:

1% it known that I, HENRY PERAzzoLI, a subject of the King of Italy, residing at 1528 S0. Juniper street, Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Track-Grinding Machines, of which the following is a specification.

The invention relates to track grinding machines and has'for an object to provide a machine for grinding the rails of a track.

The invention comprehends more particularly, a machine for grindingthe rails, by means of some abrasive substance, of a track, to successfully remove surface inequalities and corrugations that usually develop in the rails during the constant use thereof.

With this object in mind, the invention embodies a suitable frame and a carriage, with the frame adapted to be disposed in position for grinding upon the rails with the usual grinding material or substance and the carriage provided for the purpose of raising or lifting the grinding mechanism from the rails so that the entire device can be readily removed at a moments notice, for the passage of an on-coming car, it being understood that the grindingof track railsis usually carried on without hampering the service of the car line and therefore it is necessary that the grinding apparatus be quickly arranged in position, and as quickly removed, so that a proper service can be maintained.

I am aware that various forms of track grinding apparatus have been employed heretofore, and I do not aim in this instance to provide any new form of track grinding element or substance, or any structure pertaining to the actual operation of the track grinding upon the rails, but have devoted myself. more particularly to a construction which permits the ready removal and replacement of the track grinding apparatus and its replacement in grinding position on the rail.v

In the further disclosure of the invention, reference is to be had to the accompanying drawings, constituting a part of this. specification, in which similarcharacters of reference denot corresponding parts in all the views, and which-- Figure 1is a vertical sectional view taken through a portion of a track grinding riage wheels, when Specification of Letters Patent.

apparatus, showing myinvention, the section being taken on the line 1-1 in Fig. 2.

Fig. 2-is a fragmentary plan view of the structure shown in Fig. 1, and

Fig; 3is a fragmentary enlarged vertical sectional view of a portion of the operating mechanism.

Referring more particularly to the views I provide a carriage 10 consisting substantially of a plurality of wagon or similar wheels 11,'connected by a cross shaft 12 in the nature of an axle and I also provide a frame 13 carried on suitable wheels or roll ers l t to fitthe usual track 15, the frame 13 also carrying a supplementary vertical frame 16 secured at one end ofthe frame 13.

A suitable handle 17 is provided to extend from the frame 13, oneof these handles be ing'provided at each end of the frame, so that the frame and carriage .can be readily pushed or pulled toward or away from the track, as desired.

It will now be apparent that when the apparatus thus far described, is in position on a rail and it is desired to remove the same because of an approaching car, it will of course be necessary to raise the frame and in fact the entire apparatus except the carriage, from the rail so that the apparatus can be easily drawn off of the side to permit the oncoming car to pass and it will be also seen that it is v desirable to have the carriage wheels 11, provided for the purpose of permitting the apparatus to be easily wheeled out of the line of the track and which carthe apparatus is in position on the track, will-be moved out of the way or disposed in an inoperative position so that the weight of the apparatus will seat the same properly upon the track through .upon the frame 16 is an externally threaded sleeve 23, in threaded engagementwith the screw 22, and pivoted to an end of the sleeve is a link 24, having pivotal connection with the lower depending end of a bell-crank lever 25 journaled on a cross shaft 26 mounted in suitable bearings 27 on the upper part of the frame. The bell-crank lever 25 has a projecting end 28 pivotally connected to a link 29 which projects forwardly and downwardly to connect with a cross bar 30 as shown. Journaled on the cross shaft 12 of the carriage are a plurality of bell-crank levers S1 to which the ends of the cross bar 30 are suitably connected. Frame bars 32 are also journaled on the cross shaft 12 and on the shaft 26, and form connecting elements between the frame 13 and the carriage, permitting however raising or lowering of the carriage as will be hereinafter more fully disclosed. Connected to a depending end 33 of each bell-crank lever 31, is a chain 3 1, one being provided for each side, and the lower end of the chain carries a threaded bolt 35, passing through a plate 36 secured to the underside of the supplementary or grinding frame 16.

The bell crank levers 31 are formed with collars 37 and suitably keyed thereto and depending therefrom are supporting members 38, the lower ends of which carry rollers 39 adapted to operate over an inclined surface a0 of a block 41 secured to the grinding frame 13.

Now with the construction described, it will be seen that when the track grinding frame is in position over the rail 15, with the rollers 14% riding upon the rail, the carriage 10 and at least the wheels 11 thereof, will be raised from the surface of the track or ground. Now if it is desired to quickly remove. the track grinding apparatus from grinding position for the purpose of moving the apparatus out of the path of an oncoming car, it is only necessary for the operator to actuate the operating wheel 18 which will actuate the screw 22 and impart a swinging movement to the bell-crank lever 25, thus exerting a pull on the links or connecting rods 29, and operating the other bellcrank levers so as to rotate the same about the cross shaft 12. This results in a pull upon the chains 34 and at the. same time causes the supporting members 38 at their lower ends, through the medium of the roller 39, to ride down the incline 10. This operation will bring about the lowering of the carriage frame and of course the wheels thereof, to the surface and result in the raising of the supplementary or grinding frame 16 so as to raise one end thereof from the track and when this has been accomplished the workman can grasp the handle 17 and by swinging the entire apparatus to pivot upon the wheels 11, it will be seen that the other end of the apparatus carrying one of the rollers or wheels 1 1, will be raised from the ground thus permitting the workman to push the apparatus out of the track and a-wa-y from the rails so that the oncoming car will not be delayed or obstructed in its passage.

Similarly in returning the grinding ma chine to working position onthe track, the

machine is disposed so that the wheels 14 will be over the rail to be operated on, after which one end of the grinding apparatus can be lowered to rest upon the track and then a reversal of the operating wheel 18 will bring about the reversal of the mechanism described heretofore, causing the chains 3a to slacken and simultaneously cause the rollers 39 of the members 38 to ride up the incline -10, thereby lowering the grinding frame so that the other wheel 14 will touch the track and simultaneously raising the carriage wheels 11 away from the surface so that they w'll be in an inoperative position to permit operation of the track grind ing apparatus upon the rail for the purpose of accomplishing the result for which it is intended.

As mentioned heretofore I aim to provide with the structure set forth, a convenient means of moving the grinding apparatus into and out of operating position and I do not desire to limit this construction to any par ticular form of grinding apparatus; the disclosure in the drawings being merely one form of my device as applied to the standard form of apparatus now generally used, it being understood that various slight changes may be made in my construction without departing from the spirit of my invention, the scope of which is defined in the appended claims. 7

Having described my invention, I claim,-

1. In a track grinding apparatus, the com bination with a grinding frame and a carriage, said carriage including a cross shaft and wheels, of a supporting frame in the grinding frame, a bell-crank lever journaled on the cross shaft of the carriage, a connection between the bell-crank lever and the grinding frame, a cross shaft on the supporting frame, a bell-crank lever on the last mentioned cross shaft, a link connecting the mentioned bell-crank levers, a supporting member depending from the bell-crank lever on the shaft of the carriage and in movable engagement with the grinding frame, an operating wheel on the supporting frame and a screw operable by said operating wheel and having connection with the bell-crank lever on the cross shaft of the supporting frame.

2.
